if you look Nicotine up on Wiki and go to "Dependence and Withdrawal" the first line is as following:

Modern research shows that nicotine acts on the brain to produce a number of effects. Specifically, research examining its addictive nature has been found to show that nicotine activates the mesolimbic pathway ("reward system") – the circuitry within the brain that regulates feelings of pleasure and euphoria.

that "reward system" is the same as dopamine, in case you don't know what dopamine is, it is what the brain releases everytime you feel happy...

So please stop posting bullshit comments, or at least be sure of what you actually write, because otherwise it makes you look like an ass.. but thanks for making me laugh with that ridiculous comment of yours

i think you mean caffeine chump. Nicotine is a stimulant and relaxant, and you don't get addicted to nicotine in 4 fucking nights, it takes months before the amount of dopamine you release by taking in Nicotine actually gets you addicted to it which leads to the conclusion that the /b/ thread is not a 100% real story, unless if the girl mentioned in the post used to be a smoker and then quit, that would cause the nicotine patch to release very high amounts of dopamine because the body "thinks" it needs nicotine, which would actually only make her sleep even better.
